Value exactly what is it?
the regard that something is held to deserve; the importance, worth, or usefulness of something.
“your support is of great value”
So what do you get with most pest control? Is there a value, often times is an unknown because you really can’t see the result or can you? The Pest Company comes out and you may or may not see them do their work. Maybe you used to see 3 scorpions per month and now you see none. Do they talk with you or leave you notes on their service?
